Inspecting Messaging Protocols, Schemas, and Delivery Patterns

Just as there are different types of message brokers, there are also different types of communication protocols that can be used, various schemas to define messages, and different types of message delivery. Choosing the option that best fits our application’s needs isn’t always an easy task because more than one option might be applicable. As we examine the options in each category, we’ll reflect on the choices that were made for the MTAEDA application and whether another option would be better suited.

Messaging protocols

Protocols related to programmatic communication aren’t necessarily exclusive to sequentially processed code or traditional client-server web applications. Different communication patterns can be leveraged across many types of software components. In the case of components that rely on messaging in some way, there are a few protocols that make more sense than others. Let’s review those protocols in more detail.

AMQP

Advanced Message Queue Protocol (AMQP) is an open standard that was originally developed by John O’Hara that builds upon the simplicity of message queueing by focusing on the following principles:

• Message orientation

• Queueing

• Routing

• Reliability

• Security

AMQP is meant to provide a translatable protocol between various brokers and components that ...
